The plant was manually shut down at 6:04 p.m. ET on April 25 after an equipment failure occurred on one of the plant's two main transformers.

The team repaired the transformer this week and made additional modifications to its power supply to ensure future reliability. In addition, the station extended the outage to perform proactive maintenance to further ready the plant for peak summer operations.

Environmental experts also found and stopped two small leaks in underground pipes believed to be a main source of tritiated water found earlier this month in a concrete vault and groundwater on plant property. Station operators have replaced two lengths of piping, and continue to inspect pipes and a tank in the area as an added measure.

Daily samples of water from the plant's intake and discharge canals have shown no detectable levels of tritium. At no time has there been a threat to employee or public health or safety. For more information, please contact Oyster Creek Communications Manager David Benson at 609-339-9188.

Since 2000, Exelon has invested more than $100 million in the Oyster Creek's systems, components and structures to establish the platform for 20 more years of safe and reliable operations for the Garden State.

Oyster Creek is about 60 miles east of Philadelphia in Ocean County, New Jersey. The plant produces 636 net megawatts of electricity at full power, enough electricity to supply 600,000 typical homes, the equivalent to all homes in Monmouth and Ocean counties combined. In addition, plant workers, through their payrolls, are responsible for more $96 million injected directly into New Jersey's economy.
